5 Interact with a DS3231 real-time clock using the counter API and dedicated driver API.
10 The `DS3231`_ temperature-compensated real-time clock is a
11 high-precision (2 ppm) battery backed clock that maintains civil time
28 counter value is read, and its value formatted as the date, time, day of
44 is set, the civil time will be advanced to the start of the next hour,
45 and the clock will be set to align that time with the time of the boot,
46 which in the output below is 34 ms in the past. The time required to

93 The counter API callback is called at the correct time::
98 fires, at which point it displays the RTC time; the
99 nanosecond-resolution offset in seconds between the RTC time and the
100 local time; the local time from ``k_uptime_get()``; and the aggregate
101 error between local and RTC time measured in parts-per-million::
110 faster than civil time on this device. This amount of error is expected
111 for this target as the system time derives from a crystal oscillator
